Parent State ID: 9
State Depth: 6
Action Taken: put-down(block_b)
Action Reasoning: To move closer to the goal state, we need to free the hand by putting down block 'b' so that we can pick up block 'a' and place it on block 'c'.
State Description: Block 'a' is on the table and clear. Block 'b' is on the table and clear. Block 'c' is on the table and clear. Block 'd' is on the table and clear. The hand is empty.
Action Path: ['unstack(block_a, block_d)', 'put-down(block_a)', 'unstack(block_d, block_b)', 'put-down(block_d)', 'unstack(block_b, block_c)', 'put-down(block_b)']

successfully verified the action of new state 10 with the path: The last action `put-down(block_b)` is valid because its precondition (the hand holding `block_b`) is satisfied in the parent state, and the effects are correctly reflected in the current state. The current state's description and visualization accurately represent the state after the sequence of actions. All objects from the initial state are present, and their statuses are correctly visualized.
